The traditional application of pile driving steel pipes is mainly in the construction of bridges, roads, and foundation cast-in-place piles for high-rise buildings. The structure is simple and fast, which has won the favor of engineering. In recent years, with the development of offshore deepwater terminal projects, the application of pile driving pipes has become more widespread. As the main bearing capacity of the pile foundation of deepwater terminals, the required pipe diameter is also increasing with the needs of engineering.
1, Super large pipe diameter, up to 5600mm, larger diameters require special customization.
2, Ultra long length, single piece can reach over 120 meters, reducing welding time and accelerating engineering.
3, The equipment refining consumes low energy and is easy to transport and produce on site.
4, Provide a professional team for on-site production and customization.
5, The self-developed medium plate spiral welded pipe unit breaks the small diameter thick wall barrier, and 45mm is no longer
Straight seam welded pipes stand out alone.
1. What other uses does spiral welded pipe have in water supply engineering besides traditional oil pipelines?
Spiral welded pipes have low cost, excellent quality, and fast production speed. At present, preliminary progress has also been made in some special application directions, such as pier piling, tank welding (oil tanks, boilers, etc.), civil air defense engineering, air ducts, drums, steel structure support, pipes for high-rise building pile foundations, bridge type filter pipes, large diameter spiral circular variable square pipes, and so on. Spiral welded pipes are gradually being accepted by more and more industries due to their low cost, high level of production automation, and simple equipment structure. They will have great potential for development in the future.
2. What are the difficulties in on-site construction of spiral welded pipe equipment?
The spiral welded pipe unit can be disassembled as a whole or in sections, with a simple structure and convenient installation. Infrastructure construction can be tailored to local conditions according to on-site facilities. In the future, the spiral welded pipe unit will enter a construction site production mode, greatly reducing engineering costs.
3. What is the diameter range of spiral welded pipe equipment that can accommodate?
welded pipe equipment can be produced separately from φ 325mm to φ 3620mm, with one machine in hand, worry free production
